mnt wah.. t11'elmeaagfqr Immagine-move- Be it known that I, FRANZ A. FULLnn, a'.ment of' the blade to prevent the' opposite citizen of the United Stated, residing in :the i city of Newark, in the county of Essex and .Sttte 'of New Jersey, have invented certain. #new and useful Improvemente in Safety- Razors, of which the following is a full, clear, -and exact description, suehas \will enable othere skilled in" the art-to which it pertains to.1nake, construct and use 'the lsame, reference being had to' vthe acoom. panying drawings, and to numerals of ref erence marked thereon, forming a part of this specification.

My invention relates to improvements in safety razors and has'. forA its' object, the production of a' safety razor having a,blade guard, a pivotally supported. blade holder in which the'blade is pivotally supported, o'andrneans for rocking the blade while in thel frame for stropping one ofthe" blade 'edges 'Without removing the blade from the frame, and means for positively adjusting i and holding the cutting edge of the' blade, in shaving position relative'to the guard teeth. Another object of my invention `is. tof'prof' vide improved. means to cause a strop to rock a pivotally-suppbrted blade holder with its pivotally Supported blade in such 'a manner as to positively7 vprevent the blade from cutting or injuring the strop. i' .A further object of my 'invention is to provide means to limit thefmovement of the blade holder in one direotion, so asto cause at stropto rock the blade in such a manner that during the stropping operation 'of the blade, the edge thereof adjaeent to the guard, is to c'o'me -in Contact with the strop only. 40' With. these .endsin View.. my invention 'consists in certain lnovelties of Constructionand" arrangements of parte as hereinafter set forth and pointed .out inithe olaims'.'

The top edge of the rear cross piece 15, together with the pinion or gear 20, a poreach to each, und connected by. a rearcross piece 15. The lower ends of the two opposite side portions 13 and 14 are apertured and bent outwardly in order to embrace the opposite side portions 2 and 3 of the body or frame 1, and to which the blade holder is pivotally connected in an 'i coivenient manner, as by means of pivxs 1 This manner of pivotally and yieldi gly connecting the blade holder support with the body A responds with the shape of the top. edges of the side portions Z and 3 of the body or 'frame l, when the parts are in the position 'illustrated in Figs, l and 3 of the draw-I glelie sideportions 13 and 1t have upper and lower holes forming bearings for the pivoted ends' of an upper shaft 17 and a lower. roller 18,' both extending transversely of the blade holder. The upper' shaft 17 and th'e lower roller 1S are connected by means of pinioiis orgears 19 and S20, so that drawing the device alongthe strop will tend to turn the said shaft 17 and when the direction of sliding the device is reversed, the shaft 17 will. be turned over according,r to the principles already well understood in the art.

The shaft 1T carries the blade holder 21, `,which holder may consist of a piece of sheet metal wrapped around the sha-ft 17, and secured thereto in any convenient or desired manner, so as to provide resilient clamping jaws QZ-and 23 to' receive the razor blade 6 between themselves, as has been common in general heretofore.

. '.lhc razor blade, as shown. is preicrabl.r made of sheet metal provided with a longitudiinllcutting edge, but I wish it to be understood that razor blades of peculiar construction may be employed:

livotally securedto a depending lug 24, formed integrall with thebody' or frame 1, by means of a' pivot E25, 4is ihe latch late 26, the inner side' of said latch plate esigned to'bear' upon the rear port-ioirof the cross piece l5 in order that when said latch plate is manipulated by means of the linger piece, 27 secured to the latch plate. the cutting edge of the blade (i is brought into an adjusted operative position relative to the guard or removed therefrom.

The latch plate is provided with an elongated protuberance 28, designed to engage with one of a series of internal teeth 29 formed on the cross piece 15, in order to provide step-like means whereby the razor b lade can be locked in its adjusted position to prevent forward and rearward displacement.

The operation of the device is as follows: When the device is to be used for stropping purposes, the blade. holder is swung up as shown in Fig. 1 ot' the c lrawings, by disengaging the latch plate fronrthe cross piece of the blade holder support; the strop is then passed over the roller 11 at one end of the frame 1 and under the roller 18 on the blade holder support and then out through and over the roller 11 at the other end ot' the frame lof the device, as clearly indicated in Fig. 1 of the drawings.

The attaching end of the strop (not shown) is hooked over any-suitable support. while its opposite end (likewise. not shown) is held in one hand. The other hand grips the handle 10 of the device, and reciprocates said device back and forth along the. strop, thereby permitting the edge ofthe blade adjacent to the guard only to be engaged with the strop. I

The. present invention provides a very efiicient and exceedingly simple safety razor, the. saine being constructed of a minimum .number of parts, which are of such shape as to lend themselves readily to manufacture by the use of suitable punches and dies from ordinary sheet metal, and which parts are reduced to the simplest operative efficiency; and further. the invention provides a safety razor in which the accidental cutting or injuring of the strop by the blade is prevented, and the stroppingnof 'but one side of the cutting edge of the blade is possible.

The longitudinal cutting ed e of a. safety razor blade is' usually providzed with two surfaces, though only one of the surfaces is used during the shaving operation, and that is the surfacel which lies against the guard and applied .to the face When shaving. Ex I'unjience has demonstrated that it is only necessary to strop tliat surface of the cutting edge lof the'blade which lies adjacent to the guard, a-nd that by so`doing, a superior edge is produced.

I claim:

1. A safety razor comprising a frame adapted to slide longitudinally of a, strop,

a roller 'ateach end of said frame,a blade holder support pivotally connectedto said .frame intermediate of said rollers, a roller nrsaid blade holder support, .a bladeholdelfiilov pivotally eonneeted to said blade holder sup portg means, earriei'l by said blade. holder sup- ]'iort for trausn'iitting rotary movenjient to said blade holder fromcsil-id roller and means lovatet). on the frame for adjusting the blade relatif-:e to the traine.
